Abstract

The invention belongs to the technical field of display and relates to a capacitive touch screen and a manufacturing method. The capacitive touch screen comprises a base plate and sensor electrodes, wherein the sensor electrodes are arranged on the base plate; each sensor electrode comprises multiple lines of first electrode sets arranged in parallel and multiple lines of second electrode sets arranged in parallel; each first electrode set comprises multiple first electrodes electrically connected in sequence; each second electrode set comprises multiple second electrodes electrically connected in sequence; each first electrode and / or each second electrode comprise / comprises peripheral electrodes and a central electrode, the peripheral electrodes are distributed on the periphery, and the central electrode is electrically isolated from the peripheral electrodes; the adjacent peripheral electrodes on the same line / column are mutually electrically connected. The capacitive touch screen and the manufacturing method have the following benefits: the coupling between the sensor electrodes of the capacitive touch screen and common electrodes is smaller, so that RC (resistor capacitor) load is reduced, the sensor electrodes are faster in charging, and the touch induction sensitivity of the capacitive touch screen is ensured.

Description

technical field

[0001] The invention belongs to the field of display technology, and relates to a capacitive touch screen and a preparation method. Background technique

[0002] Touch screen is the latest information input device at present. It can realize human-computer interaction simply, conveniently and naturally, and provide people with a brand-new method of multimedia human-computer interaction. The earth satisfies people's visual and tactile enjoyment.

[0003] According to different working principles and transmission media, touch screens can be divided into resistive, capacitive, surface acoustic wave, and infrared types. Among them, capacitive touch screens are widely used because of their high accuracy and strong anti-interference ability.

[0004] At the same time, in order to achieve thinner and lighter touch screens, there have been methods of integrating touch panel functions with liquid crystal panels, specifically including the "In-cell" method and the "On-...
